AutoMRISimQA: an automated system for daily quality control of a 3T MRI simulator
arxiv(2024)
摘要
A software system named AutoMRISimQA was developed to monitor the daily
performance of a wide-bore 3T scanner(MRI) which was designed and dedicated to
radiotherapy simulation. The system can monitor the performance of the MRI
simulator not only by using image quality indices such as signal-to-noise ratio
(SNR), uniformity, ghosting and contrast but also performing a quick check of
geometry accuracy as well as the external lasers quantitatively. It was
implemented into the daily clinically workflow in 2013 and has been used for
more than 10 years. It was also seamlessly integrated with QAtrack, allowing
continuous monitoring of the consistency of the MRI simulator's performance.
